the street lamp target standard values are respectively set as follows according to the traffic environment types: d0 =1, d1=2, d2=1.
According to actual traffic conditions, the expressway has more common unidirectional lane lines, fewer street lamps, fewer pedestrians and fewer surrounding driving vehicles. The urban roads are generally provided with a large number of unidirectional lane lines, a large number of street lamps, a large number of pedestrians and a large number of surrounding driving vehicles. The number of the common unidirectional lane lines of the rural small roads is small, the number of the street lamps is small, the number of pedestrians is small, and the number of surrounding driving vehicles is small.
Based on the actual traffic condition, the comparison value is comprehensively calculated, and the traffic environment classification standard is matched, so that the method for judging the type of the traffic environment comprises the following steps:

On the expressway, the running speed of the vehicle is more than or equal to 90km/h, the running speed is high, the number of street lamps is small, and the number of vehicles in the surrounding range of the vehicle is small. So it has the following requirements for light: the irradiation distance is far a priority requirement, and the irradiation width requirement is not very high. Therefore, the control instruction corresponding to the traffic environment type is: the lamplight system is switched into a high beam mode, and the LEDs on the two sides are turned off by increasing current, so that the optical parameters of the lamplight system are adjusted to be more than 150m in irradiation distance and more than 7m in irradiation width.

On urban roads, the number of street lamps at two sides of the road is large, the lighting condition is good, and no particularly high requirements are imposed on the irradiation distance and the irradiation width of the vehicle. So it has the following requirements for light: and adopting an initial value of optical setting of the lamp, reducing current, and turning off LEDs on two sides. Therefore, the control instruction corresponding to the traffic environment type is: and adopting an initial value of optical setting of the lamp.
On rural roads, the number of lane lines is less, the number of turning intersections is more, the lighting conditions are poorer, the emergency is frequent, the running speed of the vehicle is generally lower than 60km/h, the requirements on the lighting distance are not high, but the requirements on the lighting width are larger. So it has the following requirements for light: the LED energy of the light source is diffused, and the irradiation width is increased. Therefore, the control instruction corresponding to the traffic environment type is: the lighting system is switched into a dipped headlight mode, and the LEDs on two sides are turned on by increasing current, so that the optical parameters of the lighting system are adjusted to be more than 50m in irradiation distance and more than 14m in irradiation width.
Drivers have different lighting requirements for headlights based on their driver's traffic conditions such as highway, urban road, and rural road. According to the scheme, the intelligent headlight can be particularly enabled to output to the intelligent headlight signal instruction after being processed according to the surrounding environment data acquired by the vehicle sensor and the data of the controller, different lighting modes can be switched according to different traffic environments of the vehicle, the light irradiation requirements of a driver under different traffic environments are met, and therefore the running safety is guaranteed.
Example 2
On the basis of the embodiment 1, the embodiment provides a preferable scheme, and the specific scheme is as follows:
in the running process of the system, when the system selects a corresponding traffic environment type and then switches the intelligent headlight to a high beam, a vehicle sensor locks and tracks a detected vehicle target or pedestrian target, and a plurality of light sources of the intelligent headlight are subjected to zone control, wherein the zone control method comprises the following steps: matching a luminous area capable of being irradiated to the locked vehicle target or the pedestrian target according to the locked vehicle target or the pedestrian target and comparing the irradiation area in a high beam state, and reducing the light intensity of the luminous area; and according to the moving track of the vehicle target or the pedestrian target detected by the sensor in real time, control switching is performed among the corresponding light-emitting areas until the light intensity of the light system is restored to the preset optical parameters of the corresponding traffic environment in the high beam state after the detected vehicle target or pedestrian target is lost by the sensor.

After locking, according to a preset irradiation range which can be irradiated by a high beam mode under the condition that no target object or obstacle exists in a preset urban road mode, identifying an irradiation range shielded by the target object, and calculating an LED light-emitting area corresponding to the shielded irradiation range.
When the LED luminous area module corresponding to the target is selected, the illumination intensity is reduced, and the LED luminous area module is generally switched to a dipped headlight mode directly, and can be set to other light intensities. And the sensor tracks and records the moving track of the target object, maps a corresponding target moving path in a preset irradiation range, matches corresponding LED luminous area modules according to a plurality of LED luminous areas which the target moving path passes, and controls each LED luminous area to control the direction and the angle according to the target moving path in a corresponding time period according to the time period when the target passes each LED luminous area according to the moving path. And when the target leaves the current LED light-emitting area, the corresponding LED light-emitting area module restores to the optical parameters of the far-reaching headlamp mode preset by the urban road mode. And after the target locked by the sensor is lost, all LED luminous area modules of the intelligent headlight are optical parameters of a far-reaching headlamp mode preset by an urban road mode.
Through the preferable scheme, the car lamp can track the front car in real time, and the high beam area irradiated to the front car is switched into the low beam, so that a driver of the front car is prevented from being influenced by the high beam of the rear car, and driving safety is guaranteed. The intelligent car lamp can track the movement of the opposite car, so that the area switched from the high beam to the low beam can track the movement of the opposite car in real time, thereby avoiding the visual blind area of the opposite car caused by the high beam and avoiding traffic accidents.
